ABSTRACT:
A flexible strut device for supporting a pair of lifter wheels for a sugar beet harvester includes a mounting bracket secured to the tool bar of the sugar beet harvester. A fixed fulcrum plate is secured to the mounting bracket and is secured to a movable fulcrum plate by connector assemblies. A flexible strut having a pair of lifter wheels journaled thereon is secured to the movable fulcrum plate. The connector assemblies include horizontally disposed compression sleeves which yieldably urge the fixed and movable plate to a normal operating position and permit the movable fulcrum plate, the flexible strut and lifter wheels to be deflected upwardly or downwardly against the bias of the compression sleeves in response to the lifter wheels striking an object, such as a stone or the like.
